Inverse Ising inference with correlated samples
Benedikt Obermayer, Erel Levine
Correlations between two variables of a high-dimensional system can be indicative of an underlying interaction, but can also result from indirect effects. Inverse Ising inference i…
Periodic vs. intermittent adaptive cycles in quasispecies co-evolution
Alexander Seeholzer, Erwin Frey, Benedikt Obermayer
We study an abstract model for the co-evolution between mutating viruses and the adaptive immune system. In sequence space, these two populations are localized around transiently d…
Dynamics of a Semiflexible Polymer or Polymer Ring in Shear Flow
Philipp S. Lang, Benedikt Obermayer, Erwin Frey
Polymers exposed to shear flow exhibit a rich tumbling dynamics. While rigid rods rotate on Jeffery orbits, flexible polymers stretch and coil up during tumbling. Theoretical resul…
Longitudinal Response of Confined Semiflexible Polymers
Florian Thüroff, Benedikt Obermayer, Erwin Frey
The longitudinal response of single semiflexible polymers to sudden changes in externally applied forces is known to be controlled by the propagation and relaxation of backbone ten…
Error thresholds for self- and cross-specific enzymatic replication
Benedikt Obermayer, Erwin Frey
The information content of a non-enzymatic self-replicator is limited by Eigen's error threshold. Presumably, enzymatic replication can maintain higher complexity, but in a competi…
Escalation of error catastrophe for enzymatic self-replicators
B. Obermayer, E. Frey
It is a long-standing question in origin-of-life research whether the information content of replicating molecules can be maintained in the presence of replication errors. Extendin…
